    "abstract": "We investigate two schemes of the quantum teleportation with a $W$ state,\nwhich belongs to a different class from a Greenberger-Horne-Zeilinger class. In\nthe first scheme, the $W$ state is shared by three parties one of whom, called\na sender, performs a Bell measurement. It is shown that quantum information of\nan unknown state is split between two parties and recovered with a certain\nprobability. In the second scheme, a sender takes two particles of the $W$\nstate and performs positive operator valued measurements in two ways. For two\nschemes, we calculate the success probability and the average fidelity. We show\nthat the average fidelity of the second scheme cannot exceed that of the first\none.",
